I'd love for you to post more tutorials. I also need a little bit of help, I tried to move on and implement polygons, but it didn't work out very well. The issue with the mirror image points happens and the polygons themselves appear behind the camera. Also, at some angles, some points are drawn correctly while others aren't, creating some very odd graphical glitches. Simply not drawing out-of-scene points doesn't work, as it creates incomplete polygons. Not to mention I don't know where to begin with z-indexing.

Here's what I have so far. Mouse to look around, arrows / space / shift to move around.

Very nice. At first I thought the tutorial was a bit hard (that I didn't explain enough stuff), but apparently I underestimated you folks. =D Although, working with polygons is sort of a bitch. Especially in Love, because you simply don't have access to the sort of stuff that you want. So you need to make some compromises. However, I made vid tutorial #2, showing how to render polygons, and it basically addresses all your problems.

I very specifically did not get into the matrices themselves much, at all. Because they really are a whole tutorial series of their own. But at the same time, you can use matrices without knowing too much about them. And especially without knowing the math behind them.

Oh, the videos are gone? That's really sad. I haven't seen Oysi being active anymore, but if you somehow still see this, I think a lot of people can still benefit from those tutorials, they were really good!
